Specifications

•
Jumper Selection of Drive Output Frequency –
I
ncreases the motor speed up to two times the
r
ated RPM.
•
Ride-Through –
P
rovides smooth recovery to the previous set speed during a momentary power
l
oss (of less than 2 seconds).
•
Holding Torque at Zero Speed –
R
esists motor shaft rotation when the drive is in Stop Mode.

.2 PERFORMANCE FEATURES
•
Power Start™ –
P
rovides more than 200% starting torque which ensures startup of high
frictional loads.
• Slip Compensation with Static Auto-Tune and Boost – Provides excellent load regulation over a
w
ide speed range.
•
Speed Range –
6
0:1
3.3 PROTECTION FEATURES
• Motor Overload (I
2
t) with RMS Current Limit* – Provides motor overload protection which pre-
vents motor burnout and eliminates nuisance trips.*
• Electronic Inrush Current Limit (EICL™) – Eliminates harmful Inrush AC line current during startup.
• Short Circuit – Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
• Regeneration – Eliminates tripping due to high bus voltage caused by rapid deceleration of high
inertial loads.
• Undervoltage and Overvoltage – Shuts down the drive if the AC line input voltage goes above or
below the operating range.
• MOV Input Transient Suppression.
• Microcontroller Self Monitoring and Auto Reboot.
*UL approved as an electronic overload protector for motors.
3.4 TRIMPOT ADJUSTMENTS
• Minimum Speed (MIN) –
Sets the minimum speed of the motor. See Section 12.1, on page 22.
• Maximum Speed (MAX) – Sets the maximum speed of the motor. See Section 12.2, on page 22.
• Acceleration (ACCEL) – Sets the amount of time for the motor to accelerate from zero speed to full
speed. See Section 12.3, on page 22.
• Deceleration (DECEL) – Sets the amount of time for the motor to decelerate from full speed to zero
speed. See Section 12.4, on page 23.
• DC Injection Brake (DECEL) – When the drive is set for DC Injection Braking (Jumper J7 set to the
“INJ” position), the DECEL trimpot is used to set the DC Injection Brake voltage and time. See
Section 12.5, on page 23.
• Slip Compensation (COMP) – Maintains set motor speed under varying loads. See Section 12.6,
on page 23.
• Current Limit (CL) – Sets the current limit (overload) which limits the maximum current to the motor.
See Section 12.7, on page 24.
• Boost (BOOST) – Sets the amount of Boost which can be used to obtain maximum low speed per-
formance. See Section 12.8, on pages 24 – 25.
• Jog (JOG) – Sets the “jog” speed of the motor. Must be used with an optional Run-Stop-Jog
Switch. See Section 12.9, on page 25.
